## Graphing Calculator by Mathlab

If you're looking for a graphing calculator app that works smoothly and seamlessly, you've found it! Graphing Calculator by Mathlab is a scientific graphing calculator integrated with algebra and is an indispensable mathematical tool for students in elementary school to those in college or graduate school, or just anyone who needs more than what a basic calculator offers. It is designed to replace bulky and costly handheld graphing calculators and works on virtually any Android phone or tablet.

Furthermore, Graphing Calculator by Mathlab displays calculations as it performs them on the high-quality display of the Android device, making it easier for the user to understand the calculations and see them clearly. This app has two great strengths. First, it acts as a fine scientific calculator, but, more than that, it displays the intermediate steps of the calculations as you type. It allows the students to both watch and learn how the calculations are made and how to find the final answer. Second, the graphing ability is absolutely stunning! Not only does the calculator beautifully display the graphs, but it automatically generates the x- and y- values and displays them as well.

Free version requires internet connection and contains ads! Upgrade to PRO!

“It’s like a private school math classroom, but you are the only student.”

John

"I just love YourTeacher and the way you explain things. I felt like I was in a classroom instead of just looking at examples."

Diane

"My daughter is doing Algebra 1 in 8th Grade. She had been getting really low grades because they are moving through the material so quickly. She had a test 3 days after we bought your program and she got 94% (the highest score in the class) because we had her work through the modules over and. She really enjoys the program and her motivation is good again."

## Solve Equations Calculator

Hi Guys,

Enter an equation and this works out the solution. It basically does just what it says on the tin. So if you have homework that you need to check, then look no further.

The widget tool is taken from the selection of tools that appears on my live worksheet apps on my developer page.

Hope it proves helpful.

Cheers,
